I use slay sometimes.

I said it to a flaming homosexual once (like literally the night before I saw him breaking out into CHOREO over a HSM song), and he didn't get what slay meant. I was DISAPPOINTED.
Nobody ever gets what I mean when I say 'slay', though...
I can't think of the one I like the least...probably 'hunTy' or something, though I don't think that one was originally gay slang...or any of the slang gays use really...
